MRCP评价胰管扩张的研究进展

Advances of MRCP in diagnosis of pancreatic duct dilatation

胰管扩张可见于胰腺癌、十二指肠乳头癌、胆总管末段癌、壶腹癌、胰腺导管内乳头状黏液性肿瘤、胰腺炎、胰腺假性囊肿、Oddi括约肌功能障碍、胰腺损伤、胰腺分裂、环形胰腺、胰腺结核、腹主动脉瘤、寄生虫感染等疾病,通过对磁共振胆胰管成像(MRCP)上扩张胰管形态、程度、部位、梗阻端形态等的分析,可鉴别胰管扩张的病因。

Pancreatic duct dilatation is a common sign of pancreaticobiliary diseases and may be seen in pancreatic carcinoma, carcinoma of duodenal papilla, distal common bile duct carcinoma, ampullary carcinoma, intraduetal papillary mucinous tumor, pancreatitis, pancreatic pseudoeyst, sphincter of oddi dysfunction, pancreatic trauma, pancreas divisum, annular pancreas, pancreatic tuberculosis, abdominal aorta aneurysm, etc. It is possible to make a correct diagnosis and differential diagnosis by analyzing features of shape, extent, and location of dilated pancreatic duct. This article reviews the advances of MRCP in etiological diagnosis of dilatation of the pancreatic duct.
